Exactly why the overall incidence of shingles has been increasing, and why it’s been on the rise among adults under age 50, isn’t well understood. But there are hypotheses.Asian Sex Doll

Before the development of the varicella vaccine, most people got chickenpox in childhood. This provided immunity when they were exposed to the virus as they got older. This meant that the immune system received regular reminders to keep up defenses against chickenpox and suppress the dormant varicella virus that was hiding in their own body.Big Booty Sex Doll

But after the varicella vaccine became available in the United States in 1995, fewer children and adults were exposed to the highly contagious virus. Without this frequent exposure, which would help people maintain antibodies to the virus, the odds of varicella emerging from hibernation increased, explains Daniel M. Sullivan, staff physician in internal medicine at the Cleveland Clinic. “In the effort to make our children healthier, we have unfortunately made shingles more common in young adults.”

Another theory involves stress, which could contribute to reactivating the varicella virus in adults. In a study in a 2021 issue of the British Journal of Dermatology, researchers followed 77,310 people in Denmark, ages 40 and older, and found that people with high levels of perceived psychological stress in daily life had an increased risk of developing shingles over a four-year period.Inflatable Sex Doll

Meanwhile, there has been some research about whether environmental factors—such as higher temperatures and higher humidity levels or seasonal changes—might play a role in shingles outbreaks. But some experts find this evidence thin. “We should be careful about interpreting single studies because these correlations are not very strongly supported by the data, and there are many potential confounders,” says Ray.

“There are oodles of people who get shingles and can’t figure out what triggered it,” Schaffner says. “It’s not something external. It’s something internal that causes this virus that was hibernating in their body to reactivate and come out as shingles.”
